Product Description
Core Parameters：
- Part Number: 6685-61-1024
- Type: Centrifugal engine cooling water pump
- Material: High-strength cast iron housing + precision impeller + wear-resistant mechanical seal + bearing assembly
- Structure: Pulley drive interface, with flange mounting holes and coolant inlet/outlet ports
- Function: Forced circulation of engine coolant to maintain engine operating temperature within a safe range
Function & Application：
- Cooling Circulation: Driven by a belt, the impeller rotates at high speed to circulate coolant between the engine block, cylinder head, and radiator, dissipating combustion heat and preventing engine overheating.
- Temperature Control: Works with the thermostat to precisely regulate coolant flow, keeping the engine operating in the optimal temperature range. This avoids overheating (which causes cylinder scoring and piston damage) and overcooling (which leads to poor fuel atomization and increased wear).
- Durability & Reliability: Features a wear-resistant mechanical seal and high-precision bearings, offering corrosion and vibration resistance. It adapts to high-load, long-hour operation and ensures long-term stable performance.
- OEM Compatibility: Manufactured to Cummins original equipment standards, with perfectly matched mounting holes, interface dimensions, and drive method. It can directly replace the original 6685-61-1024 water pump without modification.
Application Scenario：
Suitable for maintenance and replacement of the cooling system in Cummins NH220 engines and corresponding construction machinery and generator sets. It is a core cooling component to ensure efficient and safe engine operation.
